X-MACH MACH Number is a speed measurement used by high performance aircraft. It is based on the ratio of the speed of an aircraft to the speed of sound under the same atmospheric conditions. When an airplane is flying at the local speed of sound, it is flying at the speed of MACH 1. Example: An airplane is flying at Flight Level 150 (FL 150) - which corresponds to a Pressure Altitude (PA) of 15'000 ft - with a Calibrated Airspeed of 400 kts. Unscrew the (B) crown, turn the upper interior rotating bezel (C) and set 15 (FL150) facing 400 kts on the lower interior bezel (D). The Mach Number indicator (E) shows you the corresponding Mach Number of 0.78 on the exterior bezel (A).

X-COPTER The Maximum Take Off Weight (M.T.O.W.) of an helicopter represents the heaviest weight at which it meets all the airworthiness requirements applicable to it. It can be reminded on the dial of the Khaki X-Copter. Celsius-Fahrenheit

E.T.O. ETO=Estimated Time Over. The ETO is the time in UTC (Coordinated Universal Time) when it is expected that the aircraft will reach a given position. It can be calculated with the Khaki ETO knowing the distance to be flown and the speed of the aircraft. By turning bezels 1 and 2 in order to set the appropriate speed, desired arrival time or planned journey duration, the Khaki ETO will allow the pilot to plan every detail of the trip ahead. Split-second function: allows the reading of multiple successive times measured from the same starting point. The flyback function allows resetting of the counter hands to zero by pressing button (B) without first stopping the timing. This function allows the user to gain some seconds in the manipulation of the chronograph, which facilitates directional calculations for pilots.

GMT AIR RACE The key feature of the Khaki GMT Air Race is its unique ‘silent countdown’. This was inspired by Nicolas Ivanoff’s personal experience of needing a visual timing function while sitting in a noisy cockpit. Its appeal certainly is not limited to the cockpit and this functionality lends itself to subtly timing the duration of anything from a fitness session to a business presentation. The wearer sets the desired countdown time with the help of the turning bezel. As soon as the minute hand reaches the countdown digit selected, the targeted time is up.

Aviation QNE QNE: is the code used to indicate that the altitude being used is that viewed on a barometric altimeter when it is set to a standard pressure of 1013,2 hPa. Since the pressure at ground level varies, so does the altitude of the aircraft. High pressure means the aircraft

is

higher

than

the

altimeter indicated, low pressure means it is lower. In a mountainous region this information can be vital. The scale on the watch allows to read the difference in altitude according to changes in pressure. The back case is engraved with the pilot "Zulu" alphabet.
